ListandPlay, an awesome YouTube Instant spin off that lets you create and share video playlists

Judging by the amount of community support, instant search is here to stay. Enthusiast web developers around the globe are scrapping together incredible Google Instant spin offs and changing the search paradigm for the better. Take ListandPlay, the latest in a series of “instant” offerings.

Credited to Jonathan Bouman, a med student and experienced web developer from Amsterdam, ListandPlay lets you create and share YouTube playlists – you guessed right – instantly. It’s really easy, you simply type in your search query and up pops a list of matching clips from YouTube. You can set it to autoplay the best match or simply select a desired video manually to play it.

To add a video to your playlists, just hit the big green plus sign in the righthand column. You can add as many clips as you like and share the list on social networking services or via a uniquely-generated URL. Check out an example playlist here.

Bouman is also the brains behind two similar projects – a Wikipedia instant search engine dubbed WikInstant and PMInstant that searches the PubMed site instantly. In addition, Bouman also created the FaceRoulette service that allows folks to cam with random Facebook users.

ListandPlay.com is the latest web app inspired by the search-as-you-type upgrade Google unveiled earlier this month. In just two weeks, three similar instant searching web apps made the headlines. Feross Aboukhadijeh, a computer science student at Standford University, created YouTube Instant, seen below, that returns YouTube video clips as you’re typing in your search query.

YouTube’s co-founder was allegedly so impressed he offered Aboukhadijeh a position with the company, but the student turned it down because he was already an intern with Facebook.

Stephen Ou, a fifteen-year old kid from the Bay Area, wrote the iTunes Instant web app that talks to iTunes API to comb through the available songs and movies in order to provide search results as you type. Seeing the success with it, he followed-up with a similar offering for iOS apps entitled the App Store Instant.
